I made a map visualizing the customer count and percentage of power outage as of 6 AM Central Time today (Monday, Jan 26), following the severe winter storm over the weekend. Nashville stands out as the hardest hit area in terms of outage numbers. Data source: PowerOutage.com.

I used satellite imagery over Nashville, TN from before (1/22) and after (1/27) the recent WinterStorm to estimate the power outage at a finer spatial scale, based on changes in nighttime radiance. Data source: NASA Black Marble Nighttime At Sensor Radiance.
